Specification forming part of Letters Patent No'. 176,909, dated May 2,1876; application filed September 9, 1875.

To all 'whom it may concern:

Be it known that we, MASON WESTON and ALBERT H. JOHNSON, both ofPontiac, Oakland county, State of Michigan, have inventedan ImprovedCombined Weeder and Seed- Drill, of which the following is aspecification, reference being had to the accompanying drawings, formingpart hereof.

Our invention consists in the combination,

. with the devices constituting the seed-drill `of the rim of the boxsleeved into the other, and provided with the series of slotted openingsa through thc rims, whereby the openings are adjustable to the size ofthe seed or the quantity desired to be dropped from each opening duringthe revolution of the box. The said box is cylindrical in form, and isfixed on the axle-shaft b, which has bearings in the Abraces B, asshown, and is ,revolved at a desired rate of speed by the belt C ruimingover the conepulley c on the said shaft b and the cone-pijl' ley dformed on the hub D of the wheel W,

which revolves in bearings in the front of the frame F, as shown. E is atrough or chute, which is sustained under the box A, and conveys theseed dropped by said box to the fur row made by the marker G. The saidmarker is attached to the chute at e, as shown, and is adjustable tomark a deep or shallow furrow, as desired, or to be raised above theground, by means of the slotted opening fin its beam g, which -works onthe screw-pin h set in the cross-brace k, and provided with the thumbnutu. The beam gis suitably braced at m, as shown. Lis a gage-rod, which isconveniently carried when the lmachine is operated as a weeder, underone of the handles, resting inthe angle or point a', and with theportion b of said blade carried'obliquely upward, andl the portion ccarried obliquely downward from said angle, as shown, and having theupright 'blades d', one on either side. The knife is carried by the longarms A', which are braced by the braces B, and are provided with theopenings e', as shown, which fit over screwpins s set in the openings fin the handles H, and provided with the thumb-nuts a', where by theknife is adjustable to suit the height of the operator and the depth anddirection of the out.

By means of the form given to the knife K, the transverse bladeoperateswith a drawcut against the weeds, instead of a direct pressure,while the upright side blades d operate' to cut away creeperlweeds,such, for instance, as nfest strawberry-beds.

When thevmachine is vin operation as a drill the parts are adjusted inposition shown in Fig. 2, and the knife K then operates as a shovel tocover the seed dropped in the furrow by the drill device.

When the machine is operated as a weeder, the parts are adjusted in theposition shown in Fig. l, the marker G- being raised above the ground,and the revolution of the drill-- box stopped. The knife K then acts tocut and uproot the weeds and scarify the ground.

We are aware that the adjustable sleeved drilLbox A is not new, and alsothat the chute E has been heretofore known and used. We do not intend toclaim either of these devices broadly7 but to limit our claim to them incombination with the specific parts and devices herein shown anddescribed-that is to say, with the cone-pulley c, the belt C, thecone-pulley d, the adjustable marker G, and the Weeder-knife K, whichperforms the double function of weeder and coverer of the seed,
